Activation
The system can be started up in
a number of ways. It is however
advisable to begin by pressing one
of the buttons 10 AUTO and using
the buttons 1 or 2 to set the desired
temperature. This way the system
will operate in fully automatic mode
so that the temperatures set will be
reached as quickly as possible.
In this condition, manual operations
will activate the following functions:
- MONO button 7 adjusts the air
temperature and distribution in the
4
two heating/air conditioning areas;
- REAR button 12 enables/disables
the air fl ow to the rear vents;
- button 6 turns off the compressor;
- button 8 activates/deactivates the
defrosting/demisting function on
the front side windows;
- button 11 activates/deactivates the
heated rear window.
By altering any other parameter
manually, such as the air temperature
or distribution, these features switch
from the fully automatic control
mode (FULL AUTO) to manual mode
(AUTO).
136
On starting the vehicle after stopping,
the various parameters are controlled
manually or automatically, depending
on the options selected by the user
before turning the engine off.
Therefore all the manual operations
performed before the vehicle is
turned off are stored and maintained
for the next start up.
This also applies for the OFF function;
if the system was in the OFF position
before turning the vehicle off, when
next started the system should still be
in the OFF position.
System deactivation
If the compressor is deactivated by
setting the air fl ow reduction control
3 below the fi rst bar, the fan will be
turned off.
When set to OFF, the heated rear
window button 11 and recirculation
button 9 are controlled normally
without activating the air
conditioning system.
Exiting the OFF mode, the
recirculation function will switch back
to Automatic mode.
Recirculation
This function is activated by pressing
button 9 and allows only the air
already in the passenger compartment
to circulate.
The recirculation function has various
operation modes:
- forced closed recirculation (LED on
button illuminated);
- forced open recirculation (LED on
button off).
